DRYING MACHl-NE FOR WOOL, 80G.

SPECIFICATION forming part of Letters Patent No. 600,805, dated March 15, 1898.

Application filed. August 9, 1897. Serial No. 647,549. (No model.)

To all whom it may concern:

Be it known that I, CHARLES W. SC WARTZ, J r., a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Drying-Machines for W001, 850., of which the following is a specification.

The object of my invention is to apply a self-feed to a continuous machine for drying W001, 630., in a more simple manner than heretofore, the object being to save the first cost in" the construction of the machine.

Heretofore self-feeds for wool-drying machines have been constructed as an attachment to the ordinary wool-drying machine, and consequently greatly increased the first cost. I accomplish the object in the following manner, reference being had to the accompanying drawings, in which- Figure 1 is a longitudinal sectional view of my improved drying-machine for W001, 850.; and Fig. 2 is a transverse sectional view.

A is the frame of the machine, which is of the ordinary construction. B is a perforated traveling belt, which passes around two beltwheels BB at each end of the machine. One of the belt-wheels is the driving-wheel for imparting motion to the belt, so that it will have a slow forward feed throughout the machine.

The machine has one or more compartments, and in these compartments are circulatingfans 0. In the present instance there are two fans in each compartment, so as to draw the air down through the belt and the material and force it up into the space above the belt, so as to thoroughly dry the wool that is carried by the belt. I

'D is an exhaust-fan for exhausting the moist air as it is collected from the material.

E is a hopper at the feed end of the machine, and F is a traveling toothed apron which carries the wool from the hopper and feeds it to the traveling belt in thin layers, so that it will be evenly distributed thereon and can be readily dried by the current of air passing through it and the belt. This toothed apron F is adapted to wheels ff and is arranged at an incline, as shown. The Wheel f is driven in any suitable manner.

Adapted to rotate in close proximity to the upper end of the belt is a shaft having blades which act upon the wool as its apron passes -over the upper Wheel f. The Wool passes from the apron onto the perforated belt, as shown, in thin layers.

7 Heretofore the belt only extended to the edge of the casing A and a separate apparatus was used to feed the wool to the apron;

but I extend the belt B past the apron and under the hopper E, forming a movable table,

so that it will act as a traveling bottom for the hopper and will feed the wool to the apron at the front and will receive wool from the apron at the rear, simplifying the construction of the machine, making it easy-running;

and the machine is not so liable to get out of order as those in which separate hopper mechanism is employed.

I claim as my invention- 1. The combination in a machine for drying wool, &c., of a drying-chamber, an apron at the feed end of the machine for distributing the material, an endless carrying-belt extending within the drying-chamber and beyond the apron at the front end of the machine forming a feed-table so that the belt will feed material to the apron and in turn will receive material from the apron at the rear thereof, substantially as described.

2. In a machine for drying W001, 850., the I the hopper, an endless perforated carryingbelt extending throughout the entire length of the chamber and forming the bottom of the said feed-hopper, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES W. SCHWARTZ, JR.
